 The prevalence of Varus knee malalignment among junior and adult football players is higher than in other sports, but no causal relationship between Genuvarum and knee osteoarthritis has been established. This study compared knee alignment measurements and sport-specific data of adolescent football players and referees to determine if there are any differences in leg axis deviation between the two groups. The results showed that the football environment with frequent football exposure seems to have an influence on leg axis deviation in junior football players compared to referees. Further research into the development of leg axis deviation in adolescents is necessary to better understand how it may lead to knee osteoarthritis.
